For those who have one of these fine machines I have seen it all. My father bought this machine in 1976 brand new and I still use today. Much of the discussion I have read is right in line with 48 years of experience running this machine. Starting a bale starts with hay in right condition that would be square baled. Filling the chamber from one side crossing windrow to the other side then back is paramount in easy starting a bale. This helps to keep from getting a large lump which is hard to get it rolling. If every effort is made to fill the chamber evenly and it still locks up and start smoking the belts. You best clean it out & check all the rollers for free movement. A stuck bearing will prevent bales from starting even when you’re doing it all right. Plus even if the bale will roll but is dragging hard a bad bearing will get hot & catch your machine on fire. I have ejected bales on fire but never the baler thank goodness.
